Schalldämpfer mit variabler Dämpfungscharakteristik

Noise absorber with variable damping characteristic, for pulsed gas flow, especially exhaust silencers

Abstract

The chamber contains a housing (2), its gas supply pipe (2), pipes (3.1,3.2) integrated in the housing, a pipe coated valve, an actuating box (10) with a diaphragm (11), spring (12), piston rod (13), and pressure connecting union, and a pressure line (6). The actuating box is of overpressure type. The pressure line feeds a gas counter-pressure to the diaphragm overpressure side. The diaphragm low pressure side is engaged by ambient pressure and the spring. The piston rod has a tight seal (14) against the housing.
